Aeronca Aircraft Corp 50 / K Srs / 60 / 65 / L-3 Grasshopper / TG-5 / O-58 / LNR-1

The Aeronca C-3 evolved into the Aeronca K Scout in 1937, the prototype being X17440.

The model 50C Chief was the first lightplane to fly non-stop from Los Angeles to New York City, on 19-39 November 1938, covering 2,785 miles in 30h 47m, avg: 90mph (registration NX21300 and piloted by Johnnie Jones).
The 1941 L-3 and O-58 Grasshopper was the military version of 65 with a greenhouse cabin and 65hp Continental YO/O-170-3. Performance and specifications were similar to the civil models. Originally designated as O-type but changed to L- in 1942. L-3D to -3J were impressed by USAAF.
The difference between the L and LA models was that the 50L had exposed cylinders, while the 50LA had a closed cowling. There were 65 50L and 20 50LA models built, some for the USAAF as the L-3.

The KM Chief evolved into the one 50M Chief built, NC21070.

The 50TC and 50TL Tandem (T-series) of 1939 were the first tandem Aeronca as competition for the Piper Cub. A total of 16 were built.

In turn, the K evolved into the SOC Chief in 1938.

In 1939, the 65-series appeared and featured the 65 hp Continental option. The 65TC Defender (112 built), a tandem two-seat trainer, was widely used throughout the war, particularly in the Civilian Pilot Training Program. The CPTP and CAP versions were the 65TAC of which 154 were built. The Model L-3, the military version of the same airplane, featured a wider fuselage and larger window area to facilitate its role as an observation plane. Although provided with dual controls, the L-3 was designed to be flown from the front seat. The observer’s seat might face forward or aft. Many of the planes reached civilian hands after World War II.
The 65C Chief and 65CA Super Chief differed by the 65CA having an optional 8-USG auxiliary fuel tank and other deluxe appointments. The 65C price was US$1,795, and the 65CA US$1,895. Of the 279 model 65C built, many were impressed by USAAF as the O-58/L-3 in 1942. A total of 655 65CA models were built.
87 of the 65LA Chief and 199 of the 65LB Super Chief model were built.

65TAF was CPTP and CAP versions of the 65TF with 59 of the 65TF built, and 115 of the 65TAF during 1940.
299 of the 65TL Tandem and 65TAL Defender were built plus military versions: 4 YO-58, 20 O-58, 701 L-3B, and 499 L-3C, plus 253 TG-5 gliders to AAF. The 65TAL was CPTP and CAP version with 100 built.
